Lindsey Pearlman's cause of death has been confirmed following an autopsy by the Los Angeles County Medical Examiner-Coroner.
Earlier this year, the former Empire cast member was found dead inside a vehicle near the entrance of Runyon Canyon Park — a popular hiking trail in Hollywood, Calif. — on Feb. 18, the date the coroner listed as the day she died. She was 43.
On Monday, the coroner officially ruled her death as a suicide caused by sodium nitrite toxicity, according to a report obtained by PEOPLE.
The report also noted that "the presence of non-toxic levels of lorazepam, metoclopramide, and codeine" were found in Lindsey's system.
Prior to her death, Lindsey was reported missing on Feb. 13. Her cousin, Savannah Pearlman, tweeted on Feb. 17 that the former General Hospital actress' phone was last pinged on Sunset Blvd. — just 1.5 miles from where her body was located near the intersection of Franklin Ave. and North Sierra Bonita Ave.
Savannah also wrote in her Twitter thread at the time that Lindsey's sister requested they share the National Suicide Hotline: 1-800-273-8255, adding, "Please know that you are never truly alone."
Lindsey's husband, Vance Smith, confirmed his wife's death on Instagram, writing, "The police found Lindsey. She's gone," before adding: "I'm broken."
The actress' rep, Michael Chiaverini, also released a statement obtained by PEOPLE following the discovery of her body.
"We are deeply saddened by Lindsey Pearlman's passing today," the statement read. "The family has asked for privacy during this difficult time while they process and grieve."

"I met the most talented people ever in the Chi," Pinnock wrote of the late actress describing Lindsey as "hilarious, goofy AF, stunning, and ridiculously gifted."
"It feels surreal that she is gone," Pinnock added.
